TOP-ROLL A nezitiii'n nee-m 5, 1

To all whom it may concr h:

Be it known that I, HERBERT G. B E E, a citizen of the United States, residing at. Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Top-Roll Saddles, of which the following is a specification.

This invention relates to certain new and useful improvements in a top roll saddle, and it. consists in an improved saddle embodying a novel lubricating device for oiling the bearing surface between the steel bearing saddle and the cast iron hub or reduced portion of the top roll.

In the spinning and twisting machine art, adead weight is used to create pressure upon the top roll, such weight being suspended from a steel saddle. In practice, it has been found that unless the saddle is kept extremely well lubricated a chatter would result by reason of the steel bearing saddle running upon the cast iron hub of the roll. This chatter produces irregularity in the drawing of the yarn, and, therefore, it. is the aim of the present invention to obviate this defect by providing a novel structure of saddle and lubricating device for supplying a lubricant between the bearing surfaces.

In the drawings- Figure 1 is a fragmentary vertical section of a roll stand depicting the improved top roll saddle.

Fig. 2 is a per 86.

Fig. 3 shows the saddle in rear elevation.

Fig. 4 is a vertical section through the upper portion of the saddle, taken on line 4-4 of Fig. 2.

Fig. 5 is a bottom plan view of the present invention as observed from line 5-5 of Fig. 4.

Referring more particularly to the drawing, the numeral 1 designates the roll stand of a spinning machine having the drawing roll 2 and the top roll 3 which is provided with a reduced or hub portion 4 for engagement by the strap 5, the latter having the weight hook 6 that is connected to the suspended weight 7 by the wire 8.

In practice,'the saddle is formed of steel and bears on the hub 4 of cast iron with the result that unless the bearing surface is ex tremely well lubricated a chatter will occur top plan view of the saddle,

b'yreason of the steel saddle running-upon the cast iron hub of the roll. A

To obviate this deficiency, aces; iron saddle 9 is secured to the underside of the weight strap 5, as by a rivet l0, and through the bearing face of the saddle is formed an oil well or pocket 11 that communicates with an oil opening 12 in the strap through a smaller passage or throat 13. In this well is a lubricant supply wicking 14 that extends upwardly through the throat into the oil opening 12. From Fig. 5 it is noted that the throat communicates with the well at the forward end thereof and that the well broadens or is given a wider lubricating area at the opposite end thereof.

The saddle is also provided with a transverse opening 15 intersecting the throat and providing for the insertion of suitable wick securing means or parts of the wick itself as well as to permit of the lubricant exuding therethrough for side lubrication.

The bearing surface of the saddle is concaved to conformably receive the hub, said saddle being provided with a finger hold or lift 16 joined thereto by the reduced neck 17 through which passes the mounting rivet 10.

This structure completely eliminates any chatter between the hub and the saddle even when the supply of oil has become exhausted through neglect or otherwise, by reason of the cast iron saddle running on the cast iron hub of the top roll. The saddle is simple of construction and very efficient in operation overcoming the defects of the ordinary saddles for top rolls, and does not require constant supervision to supply the necessary lubrication.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A top roll saddle comprising a strap from which a weight is adapted to be suspended, and a cast iron saddle secured to the strap and formed with a concave seat adapted to run upon the cast iron hub of a top roll, said saddle having an oil well in its bearing face having a smaller forward end, an oil opening formed in the strap. a connecting throat communicating with the smaller forward end of the well and with the oil opening a wicking arranged in the well and extending through the throat, and,

5 Well in its bearing face and a throat leading V therefrom, said strap having an oil opening communicating with the throat of the Well,

Wicking arranged in the well and throat, and a transversely formed openlng extend- 1 ing through the saddle and intersecting the throat.

3. A top roll saddle having a head formed witha downwardly facing oil well having lateral communicating ports, and a lubricant carrier in the well having portions extending in said lateral parts foranchoring the carrier to the head.

In testimony whereof I have signed'my name to this specification in the presence of two subscribing witnesses.
